How can I find out if my rig is chipped?

[trinafrmlv]

I just bought my Ex in January, the previous owner obviously upgraded it for towing. Im wondering how I can find out if it has been chipped?

For a 7.3 look behind your PCM behind your parking brake pedal. For all chips on 7.3's, a section of the box that holds the PCM to the firewall would be cut out & you'd be able to see either a module or chip sticking out of the opening. The only other way(which is more obvious) is if you have a knob or a dial around your steering column or on the fuse panel below your steering column. I think only tuners would plug in through the OBDII which you'd see right away.

take your parking brake off and look in there if on your pcm there isnt a black rubber thing pluggin a hole then yeah its been chipped most likely...

look at the pcm cover behind your brake pedel. it should have 2 brass looking bolts holding it together. If the bolts are missing then most likely it will have a zip tie throgh one or both holes. thats a sign someone has been in there. cut them or unscrew the bolts then you can pull the right side of the cover towards the passenger side at a 45 and see if there is a chip in it or if the black cover has been removed off the pcm

Sorry guys, I dont know the meanings of the acronyms.... what is PCM and OBDII? Please be kind, I swear Im not dumb, just new to this Thanks!

I found a little square box under the dash just above the brake pedal connected with a plastic tie. Its about a 1"x2" black plastic thing. Could that be it?

Your PCM is your computer module you were looking @ behind your parking brake pedal & your OBDII is On Board Diagnostic port, located to the center-right under your steering column just under the fuse panel. It's a port you can connect a scan tool to for Diagnostic Trouble Codes(DTCs) & also plug a tuner or programmer to.

If you see the plug still in there, chances are it isn't chipped.

sorry behind your parking brake pedal. should be a plastic cover about 2 inches wide 5 tall and 7 inches long. going to your firewall. The pcm is in there.

May sound like a dumb question, but never know without asking, does the truck have any aftermarket gauges?

Probably not, but never hurts to ask.

Boost gauge would be the Easiest way to tell. My stock 7.3 only put out like 12 or 14 pounds of boost or something. But with the programmer, it does 23-24.
